Method for manufacturing fuel cell electrolyte film-electrode bond |
摘要 |
In order to obtain an electrolyte membrane-electrode assembly using a thin electrolyte membrane, the present invention provides a production method of an electrolyte membrane-electrode assembly comprising: a step of forming a hydrogen ion-conductive polymer electrolyte membrane on a base material; a treatment step of reducing adhesion force between the base material and the hydrogen ion-conductive polymer electrolyte membrane; a step of separating and removing the base material; and a step of bonding a catalyst layer and a gas diffusion layer onto the hydrogen ion-conductive polymer electrolyte membrane, and, in order to obtain an electrolyte membrane-electrode assembly which has a catalyst without clogging and is excellent in electrode characteristics, the present invention provides a production method of an electrolyte membrane-electrode assembly comprising: a step of bonding a hydrogen ion-conductive polymer electrolyte membrane and a catalyst layer via a coating layer; a step of removing the coating layer; and a step of obtaining an electrolyte membrane-electrode assembly by forming a gas diffusion layer on the catalyst layer.
